I just happened to pic up several old issues of Fons & Porter's Love of Quilting at a thrift store a couple of weeks ago. This awesome quilt is featured on the cover of the May/June 2006 issue. Page 80 gives the pattern and this info: Quilt by Bethany Reynolds. The Stack-n-Whack method and GeoMagic fabric collection from Blank Quilting are creations of Bethany Reynolds. The pattern in a different colorway can be found here:
